| EE8915 | CO2 Sensor for Railway Applications |
| EE8915 measures reliably CO2 concentration in harsh environment and complies with the relevant railway standards. Active pressure and temperature compensation with on-board sensors leads to best CO2 measurement accuracy independent of temperature, altitude or weather conditions. | |
| Type | EE8915 CO2 sensor for duct mounting with polycarbonate enclosureEE8915 CO2 sensor for duct mounting with polycarbonate enclosure |
| EE8915 CO2 sensor for wall mounting with polycarbonate enclosureEE8915 CO2 sensor for wall mounting with polycarbonate enclosure | |
| Detail | The EE8915 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long-term stability. A multi-point CO2 and temperature adjustment procedure leads to excellent measurement accuracy over the entire temperature working range. |
| The innovative design enables the combination of short response time and high protection class. The CO2 measured data is available simultaneously as voltage and current output signal. The free EE-PCS Product Configuration Software facilitates the configuration and adjustment of the EE8915. | |
| Due to the compliance with the tough railway standards, the EE8915 stands for excellent performance in any challenging process and climate control application. | |
